Isiseko seAluminiyam pcb , ukuqhutywa kombane;

Njani ingasetyenziswa njengoko izinto PCB?

Ngenxa yokuba i-aluminium substrate yenziwe ngamanqanaba amathathu, angala: ifoyile yobhedu, umaleko wokugquma kunye nealuminium yesinyithi. kunye neendleko ze-substrate yentsimbi kufuneka nazo ziqwalaselwe.

Ngokubanzi, kuthathelwa ingqalelo indleko kunye nokusebenza kobuchwephesha, i-aluminium substrate lolona khetho lufanelekileyo.Ipleyiti yealuminium efumanekayo 6061,5052,1060, njl.Ii-substrates zeCopper nazo ziyafumaneka kwi-thermal ephezulu, ngoomatshini, ngombane nakwezinye iipropathi ezikhethekileyo, kodwa zibiza kakhulu .

Kuqhelekileyo kubonwa kumacala omabini e-aluminium substrate PCB. Elinye icala ngeoyile yokugquma lidityaniswe ngezikhonkwane ze-LED, ngelixa elinye icala libonisa umbala wokuqala wealuminiyam. Ngokubanzi, i-thermal i-conductive paste iya kusetyenziswa kwaye emva koko idibane nenxalenye ye-thermal. Enye yezona zinto ziluncedo kakhulu ze-aluminium substrates ngaphezulu kwemveli ye-FR-4 kukuba banokuphatha ubushushu obuphezulu obukhawulezayo, kunye nobushushu obuhle bokusebenza.

I-aluminium substrate inokunciphisa ukunganyangeki kobushushu kubuncinci, ukuze i-aluminium substrate isebenze ngokugqwesileyo xa kusenziwa ubushushu; Xa kuthelekiswa ne-ceramic substrate, iipropathi zayo zoomatshini zigqwesile. Ukongeza kwintsebenzo elungileyo yokusasaza ubushushu;

Isiseko seAluminiyam sinezinto ezilandelayo:

Ngokuhambelana neemfuno zokhuselo lokusingqongileyo lwe-RoHS, ilungele ngakumbi inkqubo ye-SMT enesikhundla esiphezulu sokuthwala ukujongana nokusasazeka kobushushu kwisikimu yoyilo lweesekethe, ukwenzela ukunciphisa ubushushu bokusebenza kwemodyuli, ukwandisa ubomi benkonzo, kunye nokuphucula uxinano lwamandla kunye nokuthembeka;

Ukunciphisa ukuhlanganiswa kwee-radiator kunye nezinye izixhobo (kubandakanya izinto ezinomsebenzi we-thermal), ukunciphisa umthamo weemveliso, nokunciphisa i-hardware kunye neendleko zendibano;

Le phezulu malunga iingenelo-aluminiyam zeendawana, Ndiyathemba uya uyayithanda! Thina i PCB mveliso , mamkele ukuba bajonge iimveliso zethu PCB ~
